In relation to people, they are the simplest group in a population. They have the simplest opinions, the simplest views and the simplest lifestyles. They are the unsophisticated (which is not correlated to the amount of happiness they have - in fact, living a simple life may make you even more happy than living a sophisticated one). Because these people do not think as much as a sophisticated person, they tend to be more naive and more gullible to gut feelings, and the ingrained culture and social laws that are around them. Their trust is easily earned.

In terms of politics, this can be taken advantage of when politicians use their persona and the gut feelings of their audience to gain followers, even when their policies and views might be to their disadvantage.

Congressional Republicans may not have anything to offer on health care reform but they did a nice job of getting the loudest common denominator to town meetings to shout down Democrats who supported Obama's plan.

A discrete reference in the homosexual community for a homosexual ("common") male that is both a pitcher ("highest") and a catcher ("denominator").
